Following answer may help you

perform your date ordering by your date identifier but use to_char() function in select clause and use some other identifier in select clause for date

e.g.

SELECT TO_CHAR(DISPDATE1,'DD/MM/YYYY') AS DISPDATE,
SUM(APPLCOUNT) AS APPLIED,
SUM(CONFCOUNT) AS CONFIRMED
FROM
    (
        SELECT COUNT(ID) AS APPLCOUNT,
                   0 AS CONFCOUNT,
                   STUDENT.APPLIED_ON AS DISPDATE1
            FROM STUDENT
            WHERE STUDENT.ID = P_ID
            GROUP BY STUDENT.APPLIED_ON
        UNION
            SELECT 0 AS APPLCOUNT,
                   COUNT(ID) AS CONFCOUNT,
                   STUDENT.CONFIRMED_ON AS DISPDATE1
            FROM STUDENT
            WHERE STUDENT.ID = P_ID
            GROUP BY STUDENT.CONFIRMED_ON
    )
GROUP BY DISPDATE1
ORDER BY DISPDATE1;
